6.2 Operating the system
6.2.1 About operating the system
▪ Operation procedure varies according to the combination of
outdoor unit and user interface.
▪ To protect the unit, turn on the main power switch 6 hours before
operation.
▪ If the main power supply is turned off during operation, operation
will restart automatically after the power turns back on again.
6.2.2 About cooling, heating, fan only, and
automatic operation
▪ Changeover cannot be made with a user interface whose display

temperature or the fan may stop immediately. This is not a
malfunction.
6.2.3 About the heating operation
It may take longer to reach the set temperature for general heating
operation than for cooling operation.
The following operation is performed in order to prevent the heating
capacity from dropping or cold air from blowing.
Defrost operation
In heating operation, freezing of the outdoor unit's air cooled coil
increases over time, restricting the energy transfer to the outdoor
unit's coil. Heating capability decreases and the system needs to go
into defrost operation to be able to remove frost from the outdoor
unit’s coil. During defrost operation the heating capacity on the
indoor unit side will temporarily drop until defrosting is completed.
After defrosting, the unit will regain its full heating capacity.
In case of Then

The indoor unit will continue heating
operation at a reduced level during defrost
operation. It will guarantee a decent comfort
level indoor.

use models)
The indoor unit will stop fan operation, the
refrigerant cycle will reverse and energy
from inside the building will be used to
defrost the outdoor unit coil.
The indoor unit will indicate defrost operation on the display .

Refer to the operation manual of the user interface.
6.4.1 About the air flow flap
Air flow flap types:
▪ Double flow + multi-flow units
▪ Corner units
▪ Ceiling suspended units
▪ Wall-mounted units
For the following conditions, a micro computer controls the air flow
